Correction to “Ultrasmall Prussian Blue Nanozyme Attenuates Osteoarthritis by Scavenging Reactive Oxygen Species and Regulating Macrophage Phenotype”

Abstract

The authors regret that the fluorescence microscopy images of intracellular ROS in the H₂O₂ group and USPBNPs-1 μg/mL group in Figure 3a were used with a mistake. The corrected images in the H₂O₂ group and USPBNPs-1 μg/mL group in Figure 3a are shown below. This figure mainly showed the scavenging efficiency of a series of concentrations of USPBNPs on intracellular ROS, which was used to screen out the optimal concentration of nanozyme. According to the results of fluorescence microscopy (Figure 3a) and flow cytometry (Figure 3b), the optimal concentration was confirmed to be 5–10 μg/mL. Therefore, the replacement of this image does not affect the conclusion in the paper. Figure 3. Effect of USPBNPs on ROS and inflammatory factors. The scavenging efficiency of USPBNPs on intracellular ROS examined by fluorescence microscopy (a) and flow cytometry (b), *p < 0.05, compared with the H₂O₂ group. (c) mRNA expression levels of IL-6, TNF-α, and MMP-13. The results are expressed as means ± SD (n = 3). *p < 0.05, **p < 0.01, ***p < 0.005. This article has not yet been cited by other publications.
